Silea, on the river Sile at the gates of Treviso

The municipality takes its name from the Sile, a spring-fed river that leaves Treviso and flows through Silea on its way to the Adriatic. Silea is joined to Treviso on its south-eastern side: along some streets you pass from city to municipality without noticing, while further east there are still fields, embankments and small hamlets.

The areas differ quite a lot. Streets near Treviso are within cycling distance of the city centre and feel like the inner suburbs; the outer hamlets are quiet, but you will need a car for almost everything. The river, with its regional park and paths along the banks, is one of the reasons people choose Silea. It is also the thing to check: near the Sile and the canals the report looks up the official flood hazard maps for the exact address.

Istat, the national statistics office, counts 10,501 residents, up 5.8% since 2011. The average age is 46.9, above the 46.0 of the province, and 25.1% are over 65. Foreign residents make up 6.2%. Declared incomes are above the provincial average, as is often the case in municipalities bordering a provincial capital.

In the province of Treviso the seismic hazard rises towards the north, in the hills and foothills: 4 municipalities are in zone 1 and 72 in zone 2. Silea, out on the plain, is in zone 3 along with 17 others, and the expected ground acceleration is about 0.123 g. In houses close to the water, where the water table is high, rising damp and foundations deserve a look too.

For shopping and going out there are 6 supermarkets and 58 bars and restaurants; everything else is in Treviso. The Revenue Agency (Agenzia delle Entrate) publishes the cadastral maps.

Earthquakes

For Italy's Civil Protection Department, Silea is in seismic zone 3, a zone where strong earthquakes are possible but rare. Only 18 of 94 municipalities in the province are in zone 3.

In the built-up area, the expected ground shaking (peak ground acceleration, PGA) is about 0.123 g, a moderate value: the level with a 10% probability of being exceeded in 50 years, on rock.

Even in zone 3, seismic standards apply to new buildings: for an older building, ask about the design year and any structural work.

Population

Compared with the 2011 census, the resident population has grown by 5.8%. The estimated average age is 47 years, in line with the province. 25% of residents are over 65 (the regional figure is 24%). Foreign residents make up 6.2% of the population. On average, a household has 2.3 members.

Silea is in climate zone E, with 2,367 heating degree days: heating may be switched on from 15 October to 15 April, for up to 14 hours a day. The same table puts the town hall at 7 metres above sea level.

Services

In the official Ministry of Education and Ministry of Health lists, Silea has 8 schools and 3 pharmacies. The Overture Maps data also lists 6 grocery shops and supermarkets, 8 healthcare facilities, 27 sports facilities and 2 parks and green areas.

There are 0.8 healthcare facilities per 1,000 residents, more than the province average (0.6).

Public transport

We do not yet have open public transport timetables for this municipality: the report says so explicitly, without inventing distances.

How built-up it is

Buildings, roads, car parks and other sealed surfaces cover 24.7% of the land in Silea, compared with 16.6% in the province and 11.9% in the region. In 2024 built-up land stayed almost the same.

Radon and contaminated sites

Silea is not among the radon priority areas designated by the Regione Veneto in 2025. Radon varies from building to building and can only be known by measuring it, especially on ground floors and in basements.

Official databases list one contaminated site, or site still under investigation, in Silea, and 3 more have been cleaned up or closed. The report tells you whether one is close to the address.

Landslides and flooding

Landslide and flood hazard changes from one street to the next even within Silea: the report checks the address against the ISPRA maps.

House prices

The Revenue Agency's price ranges per square metre (OMI) apply to zones, not to whole municipalities: the report gives the range for the address's zone.

Land registry

The cadastral maps for Silea are public: from the address the report finds the sheet and parcel number.

Liveability area by area

The Vicinalia liveability index runs from 0 to 100 and looks at the place, not the people who live there: services within walking distance, transport, green space, natural hazards, air, quiet, buildings and connection. Here it is worked out at the centre of each of the 74 inhabited census areas in Silea. Half of the residents live in areas scoring 63 or more.
